IPC: F02M25/07
Filed: 1977-10-03
Abstract: PURPOSE: To operate a control valve means for controlling recirculation of exhaust gas in reliable manner also at a high ground where back pressure is lowered,  through provision of a control valve unit which is operated differently with change in the height of the ground while controlling supply of vacuum from a vacuum reserving tank to the control valve means for controlling recirculation of exhaust gas.  
     CONSTITUTION: At a high ground, throttle (26) opening of carburetor is slightly increase so as to compensate for reduction of air density and resultant lowering of engine output, so that vacuum at vacuum port 25 is lowered. Vacuum supplied from the vacuum port 25 is reserved in reservoir tank 108. When the vacuum supplied from port 25 is lowered with increasing of throttle (26) opening, vacuum is supplied from tank 108 to control valve 30 for controlling recirculation of exhaust gas, via control valve means 90 operatively connected to height compensating means 110, and the exhaust gas is recirculated until vacuum in tank 108 is comsumed completely

Abstract: PURPOSE:To prevent the generation of abnormal sound at the time of contact by performing the contact engagement between a driven disc and a spring seat, and that between the spring seat and a drive plate at the time of the engagement being released respectively through buffer members. CONSTITUTION:When rotational torque is transmitted from a driving side inertia body 2 to a driven side inertia body 6, buffer members 26a, 26b more protruding than the protruding part 29 of a driven disc 18 are first brought into engaging contact with the recessed part 15a of a driving side spring seat 15a. The driven disc 18 and the driving side spring seat 15a become engaged with each other as the buffer members are gradually deflected. As their engaging force is heightened, the protruding part 29 of the driven disc 18 comes in direct contact with the driving side spring seat 15a so as to contract a coil spring 14. When the driven disc 18 is released from the engaged state, the driving side spring seat 15a starts its contact with the buffer members 25a, 25b, so that abnormal sound generated at the time of engagement can be absorbed.

Abstract: PURPOSE:To perform agitation of good efficiency in a wide viscosity range by combining a paddle vane with a helical ribbon vane. CONSTITUTION:Fluid as filled in a tank body 1, and a helical ribbon vane 4 and a paddle vane 7 are rotated respectively by driving shafts 2, 6 in mutually opposite directions as shown by arrows. Then, in the outside circumferential part of the inside of the tank, the downward axial flow is induced together with the swirling flow in the rotating direction of the vane 4 rotating along the inside circumferential wall of the tank 1 by said vane. On the other hand, in the central part of the tank 1, the above-described rotating flow is disturbed by the bafflelike effect of the vane 7 rotating in the opposite direction; at the same time, this is converted to powerful upward axial flow. As a whole, the flow circulating largely in the form of convection in an axial direction while swirling is formed. Further, the small circulating flow surrounding the vanes 4, 7 is locally formed around the vanes 4, 7, and the agitation of the fluid is accomplished by the mutual effect of each of such flow.
